Benefits of technology
"The patent text describes an electrical connector for printed circuit boards that has a unique design to prevent axial movement between connectors. The connector has a main body with a front end and a back end, and an opening extending therebetween. The front end has an inclined surface and a straight portion creating a ledge, while the back end has a generally circular cross section with a straight portion and a transition portion. The connector also includes an outer sleeve with an arm that engages the inclined portion and ledge of the connector to prevent movement. The technical effect of this design is to ensure reliable and secure connection between printed circuit boards and coaxial cables."
Problems solved by technology
These connections are known to cause a delamination of the soldered connections and the metallic traces on the PCBs themselves when the connectors are unmated due to the typically higher resistance required to unmate them.
Prior coaxial connectors used on PCBs have attempted to solve this problem by making the connection between the coaxial cable and the electrical connector easier to unmate (easier to pull), but that allowed the coaxial cable to become unmated when it was not desired, causing an unwanted interruption of the electrical systems.

Embodiment Construction
[0021]Reference will now be made in detail to the present preferred embodiment(s) of the invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
[0022]Referring to FIGS. 1 and 2, an electrical connector 10 has a first connector body 12 and a second connector body 14. The first connector body 12 has a forward portion 16 and a rearward portion 18. The forward portion 16 has a front end 20 and the rearward portion 18 has a back end 22, with an opening 24 extending therebetween. The forward portion 16 has a generally circular cross section with at least one inclined surface 26 extending from the front end 20 toward a middle portion 28 of the front portion 16. The inclined surface 26 inclines toward the outer surface 30 of first connector body 12 from the front end 20. The inclined surface 26 transitions into the outer surface 30, where there is a gene...

An electrical connector has first and second connector bodies. The first connector body has an inclined surface and the second connector body has arms that correspond to the inclined surfaces. At the end of the inclined surfaces are generally flat portions forming a ledge that prevent the connector bodies from separating. To unmate the connector bodies, one connector body is rotated relative to the other, causing the arms to move from the generally flat portion to the outer surface of the second connector to allow them to be moved axially away from one another.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to low resistance connectors for printed circuit boards, and particularly to connectors that require lower resistance to unmate the connector from printed circuit boards and only when the unmating of the connector from the printed circuit board is desired.[0003]2. Technical Background[0004]Coaxial connectors are used to connect with electrical connectors on printed circuit boards (PCBs). The electrical connectors on the PCBs are soldered to metallic traces on the PCBs, which in turn are laminated to the board material. Typical electrical connections between the PCB connector and coaxial connectors are of the push-pull type. These connections are known to cause a delamination of the soldered connections and the metallic traces on the PCBs themselves when the connectors are unmated due to the typically higher resistance required to unmate them.[0005]Prior coaxial connectors used on ...
